" The' vsteam leaving the clearance mixes with thev exhaust from' the-low pressure blades 11 ,and passes to the condenser or other exhaust.

In operation steam flows through the turbine as indicated by the arrows and at the same time steam flows through the' radial the working faces of t `telescopic relation wit and axial flowV packings. The steam flowing through the blade, stems tends to separate the blade carrying e ements, but this is counteracted or balanced b the steam acting on lie balancing disks l? and 18. Due to the addition ot the axial flowA packings, suflcient pressure `will be exerted on said disks at all tim'es for this 'pur ose and mechanical contact? cr rubbing of t e parts'is avoided.

In accordance with the provisions of the patent statutesJ I have described the principle-of operation of my invention, together with the apparatus which I now consider 'to represent the best embodiment thereof; but

-` I desireto have it understood that the apparatus shown is only' illustrative and .'that the invention can be carried outby other means.

What I claim as new and desire to secure by Letters Patent of the United States is 1. In an elastic fluid turbine, the combination of a'. air of oppositely rotating blade carrying e ements in which the low pressure portion of each is situated at one side of the high pressure portion and has an enlarged bore, a pair of balancing disks for each element which are smaller in diameter than the bore of the surrounding low pressure portion, an axial packing arranged in said bore, and a Steam chest also arranged in telescopic rela tion to said bore which supplies steam to the blades.

2. In an elastic fluid turbine, the combination of a pair ofoppositely rotating blade carrying elements inwhich the low pressure portion of each is situated at one side of the high pressure portion. and has an enlarged bore, a pair of balancing disks for each element which are smaller in diameter than the bore of the surrounding 'low pressure portion, an axial packing arranged in telescopic relation with said bore and acting on the steam issuing from between the disksf and a steam' chest arranged in telescopic relation with said bore and also the axial packing. y

3. In an elastic fluid turbine. the combnia tion of a pair of oxipositely rotating blade carrying elements in which the low pressure portion of each is situated at one sido of' the high pressure portion and has ancnhirged bore.y a chest which supplies steam to the blades and is in telesxropic relation to the bore of said low pressure clement, a pair of balancing disks, one of which is secured to a rotating element, the other being secured to the inner end oi' the steam chest, and an axial packing which receives steam from bctween the disks'and restricts iis flow and is in telescopic relation with said bere.

il. In an elastic fluid turbine, the combination ofva pair of oppositely rotating blade earrying'elementsin which the low pressure portion of each is situated at one side of the high pressure portion and has an enlarged bore, a chest which supplies steam to the blades and is in telescopic .relation to the bcre`of said low pressure element, a pair o1 balancing disks. one of which. is secured to a rotating element, the other being secured to the inner end ot the steam chest, and an axial packing which receives steam from between the disks and restricts its flow, said packing comprising two cylindrical members in telescopic relation to said bore, one of said members being carried by the rotor and the other by one of the balancing disks.
